Abstract

The application ranges of plastic moldings are increasing with recent remarkable improvement of resinoid performance, mold accuracy, and mold-processing technique. They have been applied in our daily commodities, for example, electrical appliances, car components, gear which requires high precision, and optical lenses. The thermoplastics that carry out the melting-solidification molding are more excellent than the thermosetting plastics that are accompanied by curing. Therefore, this can recycle and shorten the molding cycle. Fiber Reinforced thermoplastics (FRTP) have high specific strength and rigidity. For the reinforcement of FRTP, glass fibers and carbon fibers are mainly used. However, the treatment after usage is difficult, and environmental damage is large. Therefore, natural fibers are focused on b
